2 Claims.

The present invention relates to an apparatus H for moving earth and thelike and it consists in the combinations, constructions and arrangementsof parts herein described and claimed.

Generally there is provided an apparatus for the moving of sand, graveland like materials and it consists of a water inlet pipe which isconnected with a fitting of the T-type. The water inlet pipe terminatesin a nozzle of novel construction within the fitting. is connected tothe fitting in longitudinal alignment with the water inlet pipe and asuction pipe is also connected to the fitting but at right angles to thepreviously mentioned pipes. When a jet of water projects from the nozzleit causes a suction in the suction pipe and at the same time forces anymaterial which may be delivered to the fitting from the suction pipethrough the outlet pipe. The apparatus is particularly useful forremoving sand and gravel from crevices, creek beds and the like and mayalso be adapted to the dredging of bay and river bottoms or the like.

It is accordingly an object of the invention to provide a device of thecharacter set forth which is simple in construction, inexpensive tomanufacture and yet effective and efficient in use.

Another object of the invention is the provision of. a novel fitting andassociated parts forming parts of the invention.

Another object of the invention is the provision of a novel waterspreader forming a part of the invention.

A still further object of the invention is the provision, in a device ofthe character set forth, of novel means for imparting a whirling motionto a jet of water.

Other and further objects of the invention will become apparent from areading of the following specification taken in conjunction with thedrawing, in which:

Figure 1 is a side elevational view, partly broken away, of anembodiment of the invention,

Figure 2 is a sectional view, partly in elevation, taken along line 2-2of Figure 1,

Figure 3 is a sectional view taken along line 3-3 of Figure 2, and

Figure 4 is a fragmentary perspective view, somewhat enlarged,illustrating certain vanes forming a part of the invention.

Referring more particularly to the drawing, there is shown therein aT-fitting It in one end of which is threaded a collar I l whose outerportion is interiorly threaded, as indicated at l2.

An outlet pipe A nozzle I3 is provided with exterior threads It in itsouter portion for threading the same into the threads I 2 and the nozzleI3 extends inwardly of the collar II and terminatesapproximatelycentrally within the fitting I 0. A water supply pipe I5 is threadedinto the outer end of the collar II, utilizing the threads I2 for thispurpose and the collar II is provided with an integrally formed nut headIS.

The stem I? is centrally and longitudinally positioned in the innerportion of the nozzle I3 and is affixed at its rear end to a pair of outwardly extending vanes I8 whose outer ends are affixed to the innersurface of the nozzle l3, preferably by welding. The extreme inner endof the stem I1 is provided with an integrally formed spreader head I9having a frustro-conical surface 20 which presents its smaller portiontoward the innermost end of the nozzle I3.

Connected to the fitting I!) in longitudinal alignment with the nozzleI3 and supply pipe I5 is what may be termed a delivery pipe 2| andconnected to the fitting I 0 perpendicularly to the pipes I5 and El is avacuum pipe 22.

In operation, it will be apparent that water may be supplied to thenozzle I3 to the pipe I5 and that in passing through the nozzle I3 thewater will be given a whirling motion by means of the vanes l8, each ofwhich is provided with a curvular pitch and that thereafter suchwhirling water will emerge from the innermost end of the nozzle I3 toimpinge against the frustroconical surface 20 of the spreader head I9 tothereby be evenly distributed within the fitting l0 and in a directiontoward the delivery pipe 2I.

It will also be apparent that such action will create a suction in thepipe 22 and that the pipe 22 may be placed at its other end in anymaterial which is desired to move through the pipe 22 and thence throughthe pipe 2| to another position. It will also be seen that the pipe 22may be flexible in nature so that its free end may be manually orotherwise moved from place to place to make the operation of theapparatus more facile. The device will work equally as well with liquidssuch as mud, muck or the like as well as with powdered and granularmaterial such as gravel or sand since the whirling action of the wateremanating from the nozzle I3 will encompass all particles coming intothe fitting Ill from the vacuum pipe 22 and force the same through thedelivery pipe 2i. The pressure of water entering the pipe I5 may beregulated in conventional manner to suit the particular needs of anyoperation.

While but one form of the invention has been shown and described herein,it will be readily apparent to those skilled in the art that many minormodifications may be made without departing from the spirit of theinvention or the scope of the appended claims.

What is claimed is:

1. An. apparatus of the character described comprising a T-fitting; awater supply pipe connected to said fitting, a delivery pipe connectedto said fitting in longitudinal alignment with said water supply pipe, avacuum-pipe connected to said fitting perpendicularly to said Watersupply pipe and said delivery pipe, a nozzle connected to said watersupply pipe and having" its open end positioned in said fitting, alongitudinally extending stem positioned in the inner end portion ofsaid nozzle, a pair of vanes each having a curvular pitch afiixedcentrally to said stem and at their outer edges to the inner wall of.said nozzle, said stem extending out. of. the open end of said nozzle,and a spreader head aiiixed to the free end of said stem.

2. An apparatus of the character described comprising a T-fitting, awater supply pipe con- 25 nected to said fitting, a delivery pipeconnected to said fitting in longitudinal alignment with said watersupply pipe, a vacuum pipe connected to said fitting perpendicularly tosaid water supply pipe and said delivery pipe, a nozzle connected tosaid water supply pipe and having its open end positioned in saidfitting, a longitudinally extending stem positioned in the inner endportion of said nozzle, a pair of vanes each having a curvularpitch"affixed centrally to said stem and at their outer edges to the innerwall of said nozzle, said stem extending out of the open end oi saidnozzle, and a spreader head afiixed to the free end of said stem, saidhead having a frustro-conical portion presenting its smaller end towardthe openend of said nozzle.
